Nico Muller ended MW Arden's run of fastest laps in GP3 winter testing this week by topping the times this afternoon at Jerez.
Jenzer Motorsport driver Muller – who scored two victories this year on his way to third in the championship – lapped the Spanish circuit in 1m35.858sec to knock MW Arden's Michael Christensen, who drove for ART yesterday, off the top spot by just over a tenth of a second as the session drew to a close. This ended a good day for the 18-year-old, who posted the third-fastest time this morning.
The earlier session was topped comfortably by MW Arden's Simon Trummer, whose 1m34.496sec was nearly two tenths quicker than Mucke's Nigel Melker. Trummer's stellar performance followed Antonio Felix da Costa's clean sweep for the same team at Jerez yesterday. The Portugese driver was back today driving for Tech 1 Racing, alongside Formula 3 Euro Series driver, Alexander Sims.
With moral support on hand from his two-time World Rally Championship winning father, Carlos Sainz Jr. made a low-key GP3 testing debut with the Addax team. He finished a solid 13th in his GP3 debut this morning, but was unable to better his 1m35.529sec fastest lap, and was nearly two seconds slower in the afternoon.
Spa race winner Adrien Tambay returned to action with Manor Racing, whilst Hockenheim polesitter Josef Newgarden continued his development work with Carlin.
